SAN DIEGO — A robber who helped ambush and kill a Border Patrol agent in a plot to obtain his night vision goggles was sentenced Thursday to 40 years in prison.
Emilio Gonzales Arezanas was the fourth man to be sentenced for the robbery-gone-wrong, and potentially the last. A fifth remains at large, although he is believed to be dead.
Agent Robert Rosas was a 30-year-old married father of two when he was shot at least nine times in the Campo desert on July 23, 2009.
